ADS4246IRGCT

Analog To Digital Converters (ADC) Overview

The ADS4246IRGCT is a dual-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 80 MSPS with a pipeline architecture and differential input type. The device utilizes parallel CMOS output interfaces and requires 3.3 V for the analog supply and 1.8 V for the digital supply. Key performance metrics include a signal-to-noise ratio (SNR) of 72.6 dB and an effective number of bits (ENOB) of 11.5 bits. It functions within a temperature range of -40°C to +85°C and is housed in a VQFN-64 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRGCT corresponds to the VQFN-64 package and tape-and-reel shipping format. Confirm RoHS compliance status through the manufacturer's official documentation before procurement. Ensure the ordering part number matches the required temperature grade and pinout configuration for the target application board.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between 14-bit resolution and moderate speed is required. Compare SNR and power dissipation against similar models like the ADS4242 or ADS4249 if higher throughput or lower noise is needed. Verify that the 3.3V analog supply aligns with the system power architecture.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS42xx family of low-power, dual-channel ADCs from Texas Instruments. These components are designed for applications requiring multiple channels without excessive power draw. The ADS4246 specifically targets mid-range performance needs compared to the higher-speed ADS4249 or lower-speed ADS4242 within the same series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same package and pinout include the ADS4242IRGCT and ADS4249IRGCT. Verify compatibility regarding sampling rate differences and power specifications before swapping.
